Support for Hamlib

[rnbokade]

Basically just like -a is for sending easycomm protocol data on serial. Simply we can make something like -r and -m where we can add the port number where hamlib is running. In background these will keep sending frequency and az-el values to hamlib port in the prescribed format. This will enable predict to be just a complete solution for making completely automated full stack gs system. Compatible with most famous rigs and rotator systems.
